SWITCHING DEVICE FOR ELECTRIC LAMPS.

Application filed August 3, 1908.

Specification of. Letters Patent.

Patented May 18, 1909.

Serial No. 44:6,690.

T 0 all 1071 0m it may concern:

Be it known that I, CHARLES A. EIMER, a citizen of the United States,residing at Los Gatos, in the county of Santa Clara and State ofCalifornia, have invented certain new and useful Improvements inSwitching Devices for Electric Lamps, of which the following is aspecification.

My invention relates to an improvement in switching devices for electriclamps, and the object is to provide means, which is attached to the bulbof the lamp, for throwing it into and out of circuit by simply turningthe bulb in the socketf" The invention consists of certain novelfeatures of construction and combinations of parts which will behereinafter described and more fully pointed out in the claims.

In the accompanying drawings :Figure 1 is a perspective view Fig. 2 is atransverse, horizontal, sectional view; and Fig. 3 is a de tail.

A represents the lamp socket, and B is an incandescent bulb received inthe socket. A shade bracket 1 is mounted upon the socket having twotubes 2, 2 connected thereto.

T he clamp 3 of metal wound with cord or other suitable material isconnected to the lamp bulb, and an eyelet 4 is formed on the clamp.Connected to the eyelet is a string 5, the ends of which pass up throughthe tubes and extend downwardly, one strin having a dark ball and theother a light bafi attached thereto, so that when the dark ball ispulled the bulb is turned or rotated, thus breaking the circuit, andwhen the light ball is pulled the circuit is made producing a light.

From the foregoing it will be seen that I have provided a very simpleattachment whereby the circuit can be made and. broken by simplyrotating the bulb by means of the strings. Of course, a chain might beat tached to the eyelet and one end of each chain inserted through atube.

It is evident that more or less slight. changes might be resorted to inthe form and arrangement of the several parts described withoutdeparting from the spirit and scope of my invention, and hence I do notwish to be limited to the exact construction herein set forth, but:

Having fully described my invention, Wh at I claim as new and desire tosecure by Letters Patent, is:

1.. A switch device for electric lamps comprising a lamp socket, a lampbulb connected thereto, a clamp connected to the bulb, and meansengaging the clam. for rotating the bulb for making and brea ring thecircuit.

2. A switch devfce for electic lamps comprising a lamp socket, a bulbconnected thereto, a clamp connected to the bulb, a lamp bracketconnected to the socket having openings formed therein, and means connected to the clamp and passing through the openings in the bracket forrotating the bulb for making and breaking the circuit.

3. A switch device for electric lamps comprising a socket, a lamp bulbconnected thereto, a shade bracket connected to the socket, tubesconnected to the bracket, a clamp connected to the bulb, a stringconnected to the clamp, both ends of the string passing through thetubes, and one string being for rotating the bulb for breaking thecircuit and the other for making the circuit.

4. A switch device for electric lamps comprising a socket, a lamp bulbconnected thereto, a shade bracket connected to the socket, tubesconnected to the bracket, a clamp connected to the bulb an d having aneye thereon, a string connected to the eye of the clamp, both ends ofthe string passing through the tubes and one string being for rotatingthe bulb for breaking the circuit and the other for making the circuit.

In testimony whereof I aflix my signature, in the presence of twowitnesses.

CHARLES A. EIMER.
